MOLD FOR MAKING ART FioaAL STONE.

Specification of Letters Patent. Application filed Julie 26.1905. Serial No. 267,016.

Patented J une 26, 1906,

-Missouri, have invented certain new and useful Improvements in Molds for Making Arti ficial Stone, of which the following is a speci- I of the side and end members.

the side and end members are shown in dot-' line a. b of Fig. 3. Fig. 5 is a plan view of theher shown having a plain face.

fication.

My lnventlon relates to improvements in molds for making artificial-stone blocks "or columns.

The object of my invention is to provide a mold which may beadapted to form blocks or columns. of difierent dimensions, means being provided by which the sides of the mold may be horizontally adjusted relative to each other, so as to produce-blocks of different Widths and lengths.

My invention is adapted to be used in the production of blocks or columns having plain or fancy faces.

The peculiaritiesof my invention inafter fully described and claimed.

In the accompanying. drawings, Fi e 1 is a perspective view of the mold, the si e mem Fig. 2 is a top view of the mold shown in Fig. v1, the cores being removed" and a dividing-plate shown. In this View the right-angled member is partly broken away to show the hooks In this view are hereted lines as being partly removed. Fig. 3 is a horizontal sectional view of portions of the side and end members and showing the device for locking said members together. Fig. 4 is a vertical section-taken on thedotted mold, showing as a" part thereof the side member having a rock face. Fig. 6 is a vertical sectional view of a portion of the mold, taken longitudinally and centrally through one of the cores. Fi 7 is a perspective view of the dividing-p ate. Fi 8 is a side elevation of the plain side mem er. Figs. 9

and 10 represent, respectivel two side members of difierent lengths,.eac havinga fancy pr rock face. f

Similar characters of reference denote similar parts. 1

' 1 denotes the ordinary sup orting-plate,

sometimescalled the pallet, upon which rest the sides of the mold. Uponthe supporting-plate 1 is mounted a right-angled vertical member, the two arms 2 and 3 of v which form, respectively, one side and-oneI end of the mold. The side arm 2 is provided with a longitudinally-arranged series of holes 4, disposed one row above the other. The end arm 3 is provided with two rows of holes 5, similarly arranged.- The end member 6 comprises a vertical plate provided with two hooks 7, dis osed at one end, one above the other, and a apted to enter, respectively, the holes in the upper and lower rows of the side arm 2. The member 61's provided with two rows of holes 8, arranged longitudinally one= row above the other and adapted to receive therein, respectively, two projections 9, eachprovided with a lateral notch 10. Two keys, preferably wedge form and denotedby 11, are adapted to be mounted upon the outer side of the member 6 in the notches 10,.

respectively. The projections 9 are at one endof a side member comprising a vertical longitudinally-arranged plate 12, the other end of which is provided with two hooks 13, adapted to enter, respectively, the holes 5 in the arm 3. v r

14 denotes two vertical rectangular downwardly-tapering cores adapted to be placed upon the plate 1 between t e different members forming .the sides of the mold. The

lower end of each core '14 is provided With 8.-

plurality of-vertical pins 15, adaptedv to be inserted in holes 16, provided in the late 1. The side member 12 is provided w1th two rows of ho1es17, disposed in longitudinal rows, one row above the other.

18 and 19 denote, respectively, two side members, one lon er thanthe other, each provided with a" roc lr-face ar d each having at.

one end the projections 9 and at the other end the hooks 13. The lates 12, 18, and 19 are interchangeable, en one of. these is used, the end member 6 has the hooks 7 inserted in those holes 4 which-are disposed to hooks 7 in the proper holes .4 and then swung to a position in which the projections 9 will enter the proper holes 8;, after which the ke s 11' are inserted in the notches 10, thus rigid y locking the side and end members together. The cementitious material is then tampedin IIO the mold around the cores 14, after which the cores and keys 11 are removed, following which the side and end members are disengaged from each other and from the rightangled member. The right-angled member may then be withdrawn from the plate 1, after which the plate, with the molded block thereon, maybe removed and the cores, together with the right-angled member and the side and end members, may be assembled upon another supporting-plate 1 and the operation repeated. I

In column construction the plate 1 is dispensed with, the side and end members of the mold being mounted u on the top of the block previously formed, To prevent side movement of the mold members onthe plate 1, vertical pins 20, twoof which are shown. in Fig. 2, may be inserted in suitably-disposed holes in the plate 1 and outside the mold members.

When it is desired to transversely divide the block, I employ a vertical dividing plate 21., movable to difierent positions between the side arm 2 and the side member 12 and toward and from the end arm. 3. The dividing-pl'ate ,21 is provided with four projections 22, disposed twoat each end, one above the other, and adapted to enter similarly-located holes 4 and 17 in the side arm 2 and side member 12, respectively. In Fig. 2 the dividing-plate 21 is shown positioned so as to divide the block in two equalparts.

In order to reinforce them, the end and side members 6 and 12v and the two arms of theright-angled member are preferably provided upon their'outer sides and ad acent their upper and lower edges, respectively, with longitudinally-disposed angle-bans 23,

rigidly secured to the .plates forming the bodies of said members. The perforations 4,5, 8, and 17 extend transversely through said angle-bars. Various modifications of. my invention may be'resorted to without departing from its s irit. aving thus describedmy invention, what I claim, and desireto seeureby Letters Pat'- ent, is
